I have a koso egt gauge I am mounting by the speedo wondering which color wires to splice into in the wireharness that is plugged into the gauge. Looked behind the steering column for a acc plug but mine is a 2010 and didn't have it.
I tapped into the blue/red and ran a wire to the chassis. Works great but at wot there is a difference of 40* 1250/1210* after a few miles. Everywhere else they are within 10* and identical at idle and low rpm. Placed them 3.75" from piston skirt.
